Spatial distribution of mortality in pecan trees in the south-central region of the state of Chihuahua.

A considerable proportion of the economy in the south-central region of Chihuahua state is dependent on agricultural activities. The region is distinguished by semi-aridity, with the Conchos and San Pedro rivers serving as the principal sources of irrigation for agricultural activities. It is evident that one of the principal crops is the pecan tree. Notwithstanding, the productivity of these plantations can be impacted by the presence of pests and diseases, which have the potential to result in the mortality of the trees. The present study investigates the spatial distribution of orchards in which the presence of dead or dying pecan trees was investigated, as well as their main causes: The following parasites have been identified: The following parasites have been identified: The following parasites have been identified: Texas rot (Phymatotrichum omnivorum), root-knot nematodes (Meloidogyne spp.), leaf beetles (Phyllophaga spp.) and stem borers (Euplatypus spp.). The municipality with the most walnut orchards is Meoqui; however, it is the one with the fewest mortality problems, whereas Delicias has the most severe problem, as do the aetiological agents studied: Phymatotrichum omnivorum, Meloidogyne spp., Phyllophaga spp. and Euplatypus spp., which have been observed to be concentrated along its north-eastern border.
